curtain fastener and part of EUGENE FRANK SCHOELL, OF NEW BRITAIN, CONNECTICUT.

Specicaton ofLetters Patent.

Patented No'v. 18, 1919.

Application filed April 14, 1919. Serial No. 289,842.

To all whom t may concern.'

Be it known that I, EUGENE FRANK SoHoELL, a citizen of the United States, re-

siding at New Britain, in the county of Hartfasteners of the spring-type illustrated inthe inventionof my case Serial No. 168,194, filed May 12, 1917, (Patent No. 1,312,158, dated August 5, 1919.)

he invention consists of a resilient stud member made in one piece of spring metal and having a confined attaching base whose ends are returned over and free of the base and are resilient and carry the socket-en gaging spring active parts or arms, as I will proceed now to 'explain and finally claim. t

In the accompanying drawings illustrating t e invention, in the several figures of which like parts are similarly designated, Figure 1 is a plan view of /my improved a curtain held in place thereby. Fig. 2 is a plan view of the curtain fastener without the curtain.

' ber, and part of curtain,

`cular form instead of the Fig. 3 is a plan view of the socket member. \Fig. 4 is a plan view of the stud member. Fig. 5 is a plan view of the blank for the stud member. Fig. 6 isa sectional view on a larger scale taken on the line 6-6 of Fig. 1. Fig. 7 is a view similar to Fig. 6 with the parts in position for Fig. 8 is a bottom view of the socket membeing in part broken away.

My improved curtain fastener comprises asocket member 10 adapted to besecured to the curtain-"11 and a stud adapted to 'be secured Kto the woodwork, and these two members resemble and also l'dili'er from the socket member and the stud member respectively shown and described in the.

In the case of'thesocket member 10, the

opening -or hole 14 therein for engaging with the head of the stud member is of cirnon-circular form shown in the earlier case. manner of securing the socket member 10 to the curtain 11 may be employed. i In the instance shown, there s a washer-like body' 16 disengagement.

member 12" Any approved adapted t o be positioned against one face of the curtaln 11 and having a neck 17 that forms the border wall of the stud-engaging hole 14 and projects through the curtain 11, its outer end portion 19 being headed over agamstthe outer face of a washes(` 20/ that 1s positloned against the opposite face of the curtain 11.

The parts of the stud member 12 that compose the head 21 for coperating with the stud-engaging hole 14 in thesocketmernber 10 differ in details as to shape from the form shown in the earlier case to correspond to the change in shape of the socket opening or hole 14 referred to.

The stud head parts comprise two similar and mating arms 22 that are positioned and each has on its outer face an overhangf 23 that is adapted to y ing rigid tooth or lug engage with the border portion of the opening 14 to eect the engagement of the socket and stud. v

rIfhe overhanging lug 23 is formed by forcing outwardly the part of the material of the farm 22 that is just above a relatively short cross-slit 24 in the said material,` substantially as in the case of the form shown in the earlier case.

Thus, the present device is the circular form of the-opening 14 in the socket member 10, and another special feature is the constructlon and arrangement of the parts of thestud member 12, which latter will now be descri-bed. I t

As in the earlier case, the stud member 12 isformed of a single piece of strip sheet material, the end portions of which serve as as described, one special feature of the arms 22. The middle portion 25 of the screws 27 by which it is secured to the saidk support 13 so as to serve as the base for-the said stud member 12.

The stud member 12 is a symmetrical structure, as shown, and`the screw holes 26 are positioned in spaced relat1on,equid1st ant from the middle or the transverse axlal lme. The base 25, therefore comprises a central part 28 that is confined between the hold1ng screws 27 and endparts29 extendmg 'outwardly from the ends of the said confined part 28 to the outer` ends of the base 25, corresponding to the position of the folding lines 30 shown in the view of the blank in Fin". 5.

filhe said end parts 29 are unconfined and free and are therefore adapted to act and do act in each case as parts of the spring meinbers, which spring members comprise on each side all of the material outward from the end of the confined portion or part 28. Thus the inactive part is limited to confined part 28, as determined by the screw holes 26, and all of the rest of the material of the blank is free, so that the resiliency thereof may be utilized in effecting engagement with the socket member and disengagement therefrom. The portions 31 overlying the base are connected to the outer unconfined end parts 29 of the base 25 by the return bends 32 which are positioned substantially along the folding line 30, already mentinoned, and these portions 31 are connected to the lower ends of the arms 22 by the bends 33 which are approximately right angles and the position of which is indicated by the folding line 34 in the `view of the blank in Fig. 5.

rl`lie connecting portions 31 have holes 35 registering with the holes 2G in the base and larger than the said holes 26 so as to provide clearance for admitting the heads of the screws 27 for enOa infr with the base 25 Y and to avoid such engagement by the said screw-heads with the intermediate or connecting portions 31 as would interfere with the free spring movement thereof.

I prefer to have the bend 32 in the form of a U-sliape of small curvature, as distinct from a sharp return bend, andalso tohave the parts constructed and arranged so that the connecting parts 31 are normally positioned yin spaced relation to the base 25 generally, being separated therefrom by the spaces 36, so as to permit freedom of movement of the spring member or spring unit as a whole. These spaces 36 are particularly advantageous in effecting disengagement .of the socket member l()l and the stud 21,1Which disengagement is effected by springing together the arms 22. Thus, in effecting such disengagement the entire composite spring member or spring unit, as described, at veach end of the confined part 28, is active as a spring device.

As shown, the base 25 is secured to the woodwork or other support by meansof two Leaaiai screws and these are symmetrically arranged. n some cases some other means of support may be used Without adecting the operation, other than in degree. rfhus in some cases a single supporting or holding screw may be used and this may be positioned precisely at the middle of the structure.

T he advantage of the circular form of the stud-engaging opening or hole 14: lies in the fact that there is avoided a definite positioning of the part for effecting engagement, suoli as is necessary with." a non-circular form of opening.

l claim as my invention 1. A curtain fastener, comprising in coinbination a socket member having an opening of circular form and a stud member having a confined base and overlying spring elements spaced apart from said base, and a head portion in the form of al pair of arms vextending outwardly from said spring elements in spaced relation to eachother and having externally projecting rigid holding lugs on their outer faces, the said head portion being constructed and arranged so` that when' positioned in the said opening the said lugs will overhang and engage with the border wall of the said opening.

2. A. stud member formed of `a single piece of strip sheet material, comprising a confined part at the middle that serves as an inactive part and a pair of active parts positioned one on each side ofthe said confined part, said active parts comprising each an arm that serves as part of a stud structure and a portion in the form of a return bend interconnecting the said arm and one end of the said confined part, and externally projecting rigid lugs on said arms.

3. A stud member formedof a single piece of strip sheet material, comprising al confined part at the middle that serves as an inactive part and a pair o f active parts positioned one on each side of the said confined part, said active parts comprising, each an arm that serves as part of a stud structure and a portion in the form of a return bend interconnecting the said arm and one end ofthe said confined part, said confined part having a hole adjacent to each of the junctions ofthe said confined part and active f parts to receive holding screws, the active parts having clearance holes for the heads of such holding screws.
